Answer: The function is neither even nor odd

Step-by-step explanation:

Expanded: f(n) = 7n+14-3n-12

f(n)

f(n) = 7n+14-3n-12

= 4n + 2

f(-x)

= 4(-n) + 2

= -4n + 2

-f(n)

=-(4n+2)

=-4n -2

f (x) does not equal f(-x)

-f(x) does not equal f(-x)

Therefore, the function is neither even nor odd
